Bending deformation capacity of large-diameter spiral-welded tubes
(2014)Numerical simulations are conducted to define the bending deformation capacity of large-diameter spiral-welded tubes, towards efficient strain-based design. Under bending loading, the principal failure mode of those tubes ... -
Dynamic simulations of an encapsulated microbubble translating in a tube at low capillary and Reynolds numbers
(2021)The dynamic translation of a micron-sized encapsulated bubble is investigated numerically inside a horizontal tube where liquid flows under constant pressure drop, when the effect of gravity is neglected. The coating of ... -
Experimental and numerical investigation of the bending capacity of spiral-welded steel tubes
(2016)To investigate the structural behaviour of large-diameter spiral-welded steel tubes under bending, a full scale experimental program has been performed, consisting of thirteen 42-inch diameter, spiral-welded steel tubes ... -
Finite element analysis of damage in pipeline bends
(2010)The present paper describes a numerical formulation for the analysis of damage in steel pipeline bends. In particular, the numerical implementation of Gurson plasticity model is described in the framework of a special ... -
The friction factor of a rarefied gas flow in a circular tube
(2007)An expression for the estimation of the Poiseuille number for internal rarefied flows is developed. The derived formula is given in terms of dimensionless quantities, which are obtained by the solution of the flow based ... -
Pipe response under concentrated lateral loads and external pressure
(2006)The paper focuses on the denting the response of pipeline segments subjected to lateral quasi-static wedge loading, in the presence of internal pressure. Nonlinear finite element models of pipeline segments, which are in ... -
Stress-corrosion cracking of a Monel 400 tube
(2004)A bent Ni-Cu Monel 400 alloy tube, which operated as part of a pipeline in a petrochemical distillery installation, failed by through-thickness cracking. The pipeline was used to carry a stream of gaseous hydrocarbons ... -
